Applicalionliled March 9, 1886. Serial No. 194,539. (No model.)

To all whoml it may concern,.-

Be it known that I, JOHN H. FELT, a citizen of the United States, and a resident of Greenfield, in the county of Hancock and State of Indiana, have invented certain new and useful Improvements in Hay-Rakes; and I do hereby declare that the following isa full, clear, and exact'description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in whichi Figure 1 isa perspective View of my improved horse hay-rake. Fig. 2 is a top view of the same. Fig. 3 is a bottom view. Fig. I is a vertical sectional view on line w x, Figs. 2 and 3. Fig. 5 is a perspective detail view of the trip mechanism, and Fig. 6 is an axial sectional view of the saine.

Similar letters of reference indicate corresponding parts in all the gures. y t

My invention has relation to self-dumping hay-rakes; and it consists in the improved construction and combination of parts of the same, as hereinafter more'fully described and claimed.

In the accompanying drawings, the letters A A indicate the thills of t-hel rake-frame, which are connected at their rear ends by a cross-head, B, bearing the clearer-teeth C, and at a distance from their rear ends means of a cross-piece, D, having a longitudinal framepiece, E, connecting the cross-piece and the cross-head near their middles.

The axle F isjournaled in bearings under the rear ends of the thills, and has the wheels G G secured to its ends, and the upper sides of the rear ends of the thills are provided with perforated lips H, upon which lips I, project ing downward from the rake-head J, are pivoted, the said rakehead having the curved teeth K and a re-enforcing cross piece or bar, L, through which the teeth pass.

The axle is provided with a chain wheel, M, over which passes a chain, N,which passes over a similar chain-wheel, O, upon a shaft,

P, journaled in bearings in one of the thills and the frame-piece E. fIheI chain -wheel turns freely upon this .tripshaft,and is formed upon its outer face with a number of ratchetteeth, Q, forming a half-clutch, and the inner endof the trip-shaft is provided with a crank, Y

R, to which the forward end of a connectingrod, S, is pivoted, the rear end of which connecting-rod is pivoted between two perforated lips, I T, upon the upper side of the rakehead. A half-clutch, U, having registering.

ratchet-teeth, slides upon a feather or key upon the tripshaft, turning with it, and is formed with a iiange, V, and with a lug, WV, projecting from its outer face and registering with the crank upon the shaft.

A spring, X, is secured at its forward end to the cross-piece connecting the thills, and

the rear end of this spring engages the flange p on the halfclutch, forcing it outward, and the inner face of the bearing Y upon the thill, in which the outer end of the trip-shaft is journaled, is formed with notches Z and A-one at the upper and one at the lower portionof the said face ofthe bearing, diametrically opposite to each other-and the lug upon the outer face of the half -clutch may enter either of these notches.

The square head B upon the inner end of a bolt, C', fits and slides in the upper notch, the

bolt sliding in a transverse perforation in the upperportion of the bearing, and having its outer end projecting at the outer face of the same. 'Ihe inner edge of an arm, D', bears against the said outer end of the bolt, and the arm is pivoted at its inner end upon the up per side of the thill to the rear of the bearing, and has its forward end bent inward, as shown at E.

A lever, F', is fulcrumed upon the outer side of the thill, and has its rear end provided with an inwardly-proj ecting bolt, G, pivoted to the said end and sliding in a perforation, H', in the lower portion of the bearing in the thill, the said bolt projecting with its inner end into the loweronotch, and a pin, I', )rojects from the outer side of the thill forward of the fulcrum of the lever, so that the forward arm of' the lever may bear against the end of the pin, holding the bolt forced inward and lling the notch with its inner end. It will now be seen that when'the forward end of the bent arm is drawn inward the square head of the sliding bolt will force the lug upon the outer face of the half-clutch out of the upper notch, in which it normally ts when the teeth are upon the ground, andthe teeth of the half-clutches will IOO enga-ge each other, and the half-clutch will be revolved together with the chain-wheel, causing the trip-shaft to revolve, and the crank upon the inner end of the saine. The revolving crank will, through the connectingrod, draw the rake'- head forward, dumping the hay within the teeth and thereupon again force the teeth down, and the lug upon the outer face of the half-clutch will keep the teeth of the halt-clutch and of the chain-wheel engaged, by forcing the half-clutch toward the wheel as it bears against the inner face of the bearing, unt-il the lug arrives at the upper notch, when the spring bearing against the half-clutch will force the said half-clutch outward and cause the lug to enter the notch.

then the rake is to be transported from one place to another, and the rake-teeth are to be kept permanently raised, the forward end of the hand-lever is raised slightly to disengage it from the pin, and the handle of the saine drawn inward, when the bolt in the lower notch will be withdrawn from the said notch, and the lug of the halfclutch, which has been revolved in the usual manner, will enter the said lower notch and remain there until the handlever is again pushed out to engage the pin, and the teeth will be raised when the lug remains in the notch, as the said lug registers with the crank upon the inner end of the shaft, so that when the lug is in its lower position the crank is in a corresponding position.

The arm which forces the bolt inward and thus causes the halt-clutch to engage with the ehain-wheel may be drawn inward by three different means, which l prefer to employ all together upon one rake, while, however, rakes may be constructed with any one of the three means for operating the dumping mechanism.

A treadle, J', projects upward from a short rock-shaft, K', which is journaled in a longitudinal bearing in the cross-piece ofthe thills below the driveris seat L', and the outer end oi' the shaft is provided with an arm, M', to the end of which is secured a cord or chain, N', which passes under a pulley, O', upon the forward side ofthe cross-piece, and is secured at its other end to the inwardly-bent end of the arm operating the trip mechanism. By means of this device the rake may be tripped by tilting the treadle by the foot at any desired place.

A U-shaped frame, I", is pivoted near its lower ends upon the axle straddling the wheel, and the end Q' ot' the outer arm ot' this frame projects to the side and downward, so that it may be engaged by the hay of a windrow and be tilted rearward, and a cord or chain, R', is secured to the lower end of the inner arm and passes over pulleys S' to the end oi' the arm operating the trip mechanism.

It will be seen that wh en the outer arm strikes the end of a windrow the arm will be tilted, and the inner arm will draw upon the cord or chain, drawing the arm inward and throwing the trip mechanism into gear.

A spring, T', is secured to the upper portion of the inner arm of the frame and to the cross-head yhaving the clearer-teeth, and this spring will serve to draw the frame back again when the rake has passed the windrow. A stud, U', projects from the middle of the cross-head having the clearer-teetl-i. and has a bar, V', with a longitudinal slot, "W', sleeved upon its lower end, and the rear part otl this iiat bar has a perforation, X', through which passes the lower end of a rod. Y', which is provided with a coiled spring, Z', wrapped around it, and the upper end ot" which passes through a perforated lip, A", projecting from the up per side ot the cross head, the spring bearing against the rear of the flat bar and against the lip, forcing the arm down. The for 'ard end of the bar is provided with a cord or chain, B", which passes over pulley C", and is secured to the end of the arm operatingthe trip mechanism. It will now he seen that as the hay collects in the rake it will bear against the rear arm of the flat bar, forcing the said arm up and the forward arm down, causing the said forward end to draw the cord or chain connecting it to the arm operating the trip niechanism, so thatthe said mechanism will be placed in gear and the hay dumped, when the arm will resume its normal position until the rake is again full.

The treadle is preferably used with either of the devices for operating the trip mechanism, so that the rake may be tripped, it the other devices should fail; or all three devices may be employed upon the rake, the cords or chains from the devicesnot in use being detached.

Having thus described my invention, I clai in and desire to secure by Letters .Patent ot the United States@ 1.
